    what to do

    First question No. The inverter has a 68 Volt maximum limit and two more batteries would push it over the limit and also your generator is setup for a 48 volt battery. Second question No. The inverter has a 50 volt minium limit and your generator is setup for a 48 volt battery. You are running...

    Which controller of these two would you use?

    I upgraded mine to Victron and it was one of the best decisions. I love the bluetooth and they do not have the noisy fan. In fact I am sitting on my couch now and looking at how my system is doing this morning at 9am. I am generating at this very moment, 9.3kw of power and 7.6kw is going into...

    18 month DIY project finally done: 39kW inverter power off grid system

    That is exactly what I thought when I purchased a flexible dryer hose. I put a match to it and it burst into flames. I replaced my dryer vent with a solid metal dryer vent because I did not want my house to go up in flames. I suggest the OP test a piece of the vent hose with a lighter to check...

    Battery cable shunt caused corrosion?

    The dielectric grease will prevent it. Undo all of your connections and clean them up. Apply the dielectric grease to the exterior surfaces and no more rust. If air cannot get to the metal then it prevents rust from forming.

    18 month DIY project finally done: 39kW inverter power off grid system

    If those ducts above your eg4's are what I think they are then they are highly flammable. They look like metal but they are really just plastic. You can tell how flammable they are by just taking a lighter to a piece of one and see if it catches on fire easily.

    Battery cable shunt caused corrosion?

    Rust is caused by metal being exposed to air. If you cover up the metal with a dielectric synthetic grease like super lube then it should prevent the corrosion.

    I get two power bills at my house so now I'm looking into solar.

    In my opinion, one of the first things to do is to get rid of the gas heat for the pool. I have a 7500 gallon pool in the state of Maine and are running it entirely with solar. I heat with solar and run the pump with solar. To heat the pool I am using 12 flat panel solar hotwater panels. To...

    Midnite Solar Announced their new 10kw AIO at Intersolar Today

    It is missing idle current and also weight.

    Swimming pool pump

    The Solar Panels have what is called a maximum power point. What this means is that they produce maximum current at a specific voltage. If you just connect a Solar Panel to a load then it will only produce a fraction of the power it is capable of. That is the job of the Mppt controller. In...

    Snow-Free solar

    I have 30 panels that are ground mount. When it snows, then I go out and scrape the snow off the panels. It is a pain to do, but if I don't do it then power production is zero or close to it until the snow melts. The 12 panels that are on the roof I just leave until the sun does its job...

    Maine Inspectors

    Electricians that deal with solar seem to be rare in the state of Maine. It sounds like you have ordered all your stuff or I would have suggested for you to go off grid as I have done.

    DC water heater.

    Wow, impressive setup. I am also in a northern climate and have experience in not only Solar but also Solar hot water panels. I have found that the solar panels mounted on the roof do not produce electricity until all the snow melts. The solar panels I have in the yard require periodic...

    Deciding to DIY my solar battery was one of my worst mistakes ever

    I am sorry that you experienced such extreme challenges on assembling your battery pack. I found it to be a very rewarding experience. First off, the compression thing is not for me. My Cells are not compressed and are doing fine. Top balancing wasn't for me either. It just seemed like a...

    Heat on terminals.

    I would get a multimeter and then measure the voltage drop at 150 amp load to test the crimp connections, fuse, wires etc. This will tell you where the heat is being generated. I do not like it when things get warm or hot.

    DIY garage system problems

    It could be a number of things. If your inverter is going into low voltage, then that implies that the voltage at the inverter is low when the freezers are trying to start. It could be your wire size is to small causing too much voltage drop between the batteries and the inverter. It could be...
